of arms. Two princely lines At the beginning of the 19th century, the House of Schwarzenberg was divided into two princely-titled lines (majorats). This division was already foreseen in the will of Prince Ferdinand (1652-1703). However, the absence of two male heirs until Joseph II and Karl I Philipp inhibited the execution. The senior branch, which held not only the Palais Schwarzenberg in Vienna, but also the Dominions of Scheinfeld, Krumlov, Frauenberg and Murau, died out in the male line in 1979 upon the death of Joseph III of Schwarzenberg, who was the 11th Prince of Schwarzenberg. The cadet branch, which was established by Karl Philipp, Prince of Schwarzenberg at Orlík Castle, continues to the present day. The two branches have now been re-united under the current head of the family, Karl VII of Schwarzenberg, who is the 12th Prince of Schwarzenberg. He is a Czech politician and served as Minister of Foreign Affairs of the Czech Republic. Present time Due to the unification of the family-headship under Karl VII Schwarzenberg, the fidei commissa of both the primogeniture / Hluboka line and the secundogeniture / Orlik line came under the single ownership of the last-mentioned prince. Karl VII created in the 1980s the current structure of the family belongings. The German and Austrian properties from the primogeniture were embedded (with some exceptions) into the Fürstlich Schwarzenberg'sche Familienstiftung (Princely Schwarzenberg Family-Foundation) based in Vaduz. The art collection, which includes the painting The Abduction of Ganymede by Peter Paul Rubens or an important collection of works by Johann Georg de Hamilton, is held in the separate Fürstlich Schwarzenberg'sche Kunststiftung (Princely Schwarzenberg Art-Foundation). The Czech property of the secundogeniture is held privately. The members of the family follow careers in the private or military sector. Frisian and Prussian line Michael II Baron zu Schwarzenberg (†1469), oldest son of Erkinger I (1362–1437), was married twice. First with Gertrud (Bätze) von Cronberg (†1438), from whom the princely line descends. His second marriage was with Ursula (Frankengrüner) Grüner (†~1484), from whom the Frisian and later the Prussian line originates. The children of Michael's and Ursula's alliance were never recognized by their half-siblings, as their first born son was born out of wedlock and the legitimisation only took place with the subsequent wedding. Johann Onuphrius (1513–1584), a great-grandson of Michael II and Ursula, is considered to be the progenitor of the Frisian Line. His marriage with Maria
